Question

对于那些尝试 jsdifflib 的人，知道此插件返回HTMLTableElement。现在我想尝试在我的VueJS组件上渲染/显示它。

我尝试了以下内容：

TEMPLATE

<div class="diff-container" v-html="dynamicHtmlContent" ref="auditContainer"></div>

COMPONENT

export default {
    name: 'AuditView',
    data() {
      return {
        dynamicHtmlContent: null
      }
    },
    created() {
      // code logic here and there
      this.processDataDiff(results, 0);
    },
    methods: {
      processDataDiff: function (data, index) {
        // code logic here and there
        this.displayDiff(
          JSON.stringify(object1, null, 4).replace(/\\n/g, '\n'),
          JSON.stringify(object2, null, 4).replace(/\\n/g, '\n'),
          versionId1,
          versionId2
        );
      },
      displayDiff: function (baseDoc, newDoc, baseVersion, newVersion) {
        this.dynamicHtmlContent = auditService.getDiff(baseDoc, newDoc, baseVersion, newVersion);
      }
    }
}

ES6服务

 getDiff(baseTextRaw, newTextRaw, baseVersion, nextVersion) {
   // build the diff view and return a DOM node
   return difflib.buildView({
     baseText: baseTextRaw,
     newText: newTextRaw,
     // set the display titles for each resource
     baseTextName: 'Version ' + baseVersion,
     newTextName: 'Version ' + nextVersion,
     contextSize: 10,
     // set inine to true if you want inline
     // rather than side by side diff
     inline: false
   });
 }

我已经跳过代码逻辑，但我已经检查了 dynamicHtmlContent ，这将返回为HTML对象，如下面的屏幕截图所示：

不知何故使用v-html是不可能的，因为它只在console.log(typeof this.dynamicHtmlContent);上呈现一个对象{}所以如何将它呈现给我的Vue组件？我也发现这很难转换为普通的字符串。请帮帮我。

你仍然可以使用v-html，你只需要改变你正在访问的内容。因为你得到的东西最终会成为一个真正的DOM元素，你可以做几件事。

首先，只需更改v-html即可访问元素的outerHTML property

v-html="dynamicHtmlContent.outerHTML"

或者将outerHTML直接保存到dynamicHtmlContent而不是DOM元素

this.dynamicHtmlContent = auditService.getDiff().outerHTML

您可以做的另一件事是直接通过accessing your auditContainer reference through this.$refs

附加DOM元素

displayDiff: function (baseDoc, newDoc, baseVersion, newVersion) {
  var table = auditService.getDiff(baseDoc, newDoc, baseVersion, newVersion);
  this.$refs.auditContainer.appendChild( table );
}

请注意，虽然在安装组件后必须这样做，因为尚未创建auditContainer。含义：

created() {
  // code logic here and there
  this.processDataDiff(results, 0);
},

将更改为：

mounted() {
  // code logic here and there
  this.processDataDiff(results, 0);
},

v-html演示

var table = document.createElement('table');
var body = table.createTBody();
var row = body.insertRow();
var cell = row.insertCell();
cell.innerHTML = "A test table";

var vm = new Vue({
  el: '#app',
  data() {
    return {
      dynamicHtmlContent: null
    }
  },
  created() {
    this.displayDiff();
  },
  methods: {
    displayDiff: function() {
      this.dynamicHtmlContent = table;
    }
  }
});

DOM附加演示

var table = document.createElement('table');
var body = table.createTBody();
var row = body.insertRow();
var cell = row.insertCell();
cell.innerHTML = "A test table";

var vm = new Vue({
  el: '#app',
  data() {
    return {
      dynamicHtmlContent: null
    }
  },
  mounted() {
    this.displayDiff();
  },
  methods: {
    displayDiff: function() {
      this.$refs.auditContainer.appendChild(table);
      
    }
  }
});

<script src="https://cdn.jsdelivr.net/npm/vue@2.5.16/dist/vue.js"></script>
<div id="app">
  <div class="diff-container" ref="auditContainer"></div>
</div>
